Which regional pattern is disrupted during El Niño?

💡 Explanation

Upwelling weakens along the coast because trade winds slacken, leading to a warm surface layer blocking nutrient-rich deep water; this represents a reduction in Ekman transport, therefore coastal fisheries decline rather than thrive due to nutrient scarcity.
